Frontend Developer
(Web & Smart TV)
const dev =Frontend and Smart TV developer with 10+ years of experience building cross-platform web applications. Focused on performance, scalable architecture, and maintainable code — from semantic HTML/CSS to modern JavaScript tooling and CI/CD pipelines. Experienced in white-label OTT platforms and SDK development with strong attention to product detail and code quality.
Position: Smart TV Developer
A company developing applications for Smart TVs, web browsers, and mobile devices. I specialized in creating applications for Big Screen platforms, with a focus on multi-platform development using modern web technologies. I worked in agile international team, collaborating closely with designers, architects, backend developers, and QA engineers.
Position: Smart TV Developer
A company focused on developing applications for Smart TVs, mobile devices, and HbbTV platforms. I worked on applications for Smart TV platforms (e.g., Samsung, LG), HbbTV, and PlayStation 3/4 using JavaScript, HTML, and CSS. Apps were built as single-page applications (SPA). I also contributed to the Mautilus Smart TV SDK to simplify cross-platform development.
This role introduced me to the technically exciting and relatively niche world of Smart TV development. At the time, platforms were still maturing and inconsistent across devices, posing challenges like poor performance, platform-specific bugs, and limited tooling. I worked with media players, DRM systems, and proprietary APIs — expanding my skills beyond typical frontend work. The experience shaped my growth and let me contribute to international projects in Mautilus’s agile, fast-paced team culture.
Complete development of websites for small businesses – from graphic design and full-stack implementation to hosting setup and deployment. Some projects included dynamic UI components, CMS integration (e.g., WordPress), or a custom booking system. Emphasis was placed on clean and semantic HTML, search engine optimization (SEO), and basic accessibility (a11y) best practices.
